What is net revenue retention (NRR)?
Net revenue retention (NRR) measures how much recurring revenue a SaaS company keeps and grows from its existing customer base over a period, including expansion, downgrades, and churn, but excluding new customers. Investors treat it as one of the clearest signals of product-market fit — an NRR above 100% means the existing customer base is growing revenue on its own, before any new sales. Definitions vary company to company, which is exactly why standardizing the calculation matters before a raise.
What financial metrics do Series B investors look for?
Series B investors typically diligence net revenue retention, gross and net margin, CAC and CAC payback period, LTV to CAC ratio, burn multiple, and runway, alongside a driver-based financial model that supports multiple growth and spend scenarios. What matters as much as the numbers themselves is consistency: metrics calculated the same way across every board deck and data room document, with a clear methodology behind each one.
